ABSTRACT

6-Azaindazole compounds for treating various diseases and pathologies are disclosed. More particularly, the present disclosure concerns the use of a 6-azaindazole compound or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis, fibrotic disorders, bone or cartilage diseases, and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as genetic diseases and neurological conditions/disorders/diseases due to mutations or dysregulation of the Wnt pathway and/or of one or more of Wnt signaling components. Also provided are methods for treating Wnt-related disease states.

RELATED APPLICATIONS

This application is a National Stage application under 35 U.S.C. § 371 of International Application No. PCT/US2016/045267, having an International Filing Date of Aug. 3, 2016, which claims the benefit of U.S. Provisional Application Nos. 62/200,433, filed Aug. 3, 2015, which are incorporated herein by reference in their entirety.

BACKGROUND

Technical Field

This disclosure relates to inhibitors of one or more proteins in the Wnt pathway, including inhibitors of one or more Wnt proteins, and compositions comprising the same. More particularly, it concerns the use of a 6-azaindazole compound or salts or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis, fibrotic disorders, bone or cartilage diseases, and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as genetic diseases and neurological conditions/disorders/diseases due to mutations or dysregulation of the Wnt pathway and/or of one or more of Wnt signaling components. Also provided are methods for treating Wnt-related disease states.

Background

The Wnt growth factor family includes more than 10 genes identified in the mouse and at least 19 genes identified in the human. Members of the Wnt family of signaling molecules mediate many short- and long-range patterning processes during invertebrate and vertebrate development. The Wnt signaling pathway is known for its role in the inductive interactions that regulate growth and differentiation, and it also plays roles in the homeostatic maintenance of post-embryonic tissue integrity. Wnt stabilizes cytoplasmic β-catenin, which stimulates the expression of genes including c-myc, c jun, fra-1, and cyclin D1. In addition, misregulation of Wnt signaling can cause developmental defects and is implicated in the genesis of several human cancers. The Wnt pathway has also been implicated in the maintenance of stem or progenitor cells in a growing list of adult tissues including skin, blood, gut, prostate, muscle, and the nervous system.

SUMMARY

The present disclosure provides methods and reagents, involving contacting a cell with an agent, such as a 6-azaindazole compound, in a sufficient amount to antagonize a Wnt activity, e.g., to reverse or control an aberrant growth state or correct a genetic disorder due to mutations in Wnt signaling components.

A “therapeutically effective amount” of a compound as provided herein is one which is sufficient to achieve the desired physiological effect and may vary according to the nature and severity of the disease condition, and the potency of the compound. “Therapeutically effective amount” is also intended to include one or more of the compounds of Formula I in combination with one or more other agents that are effective to treat the diseases and/or conditions described herein. The combination of compounds can be a synergistic combination. Synergy, as described, for example, by Chou and Talalay, Advances in Enzyme Regulation (1984), 22, 27-55, occurs when the effect of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. It will be appreciated that different concentrations may be employed for prophylaxis than for treatment of an active disease. This amount can further depend upon the patient's height, weight, sex, age and medical history.

A therapeutic effect relieves, to some extent, one or more of the symptoms of the disease.

“Treat,” “treatment,” or “treating,” as used herein refers to administering a compound or pharmaceutical composition as provided herein for therapeutic purposes.

It is to be further understood that for any particular patient, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed compositions.

In one embodiment, the compositions can be administered to the respiratory tract (including nasal and pulmonary) e.g., through a nebulizer, metered-dose inhalers, atomizer, mister, aerosol, dry powder inhaler, insufflator, liquid instillation or other suitable device or technique.

In some embodiments, aerosols intended for delivery to the nasal mucosa are provided for inhalation through the nose. For optimal delivery to the nasal cavities, inhaled particle sizes of about 5 to about 100 microns are useful, with particle sizes of about 10 to about 60 microns being preferred. For nasal delivery, a larger inhaled particle size may be desired to maximize impaction on the nasal mucosa and to minimize or prevent pulmonary deposition of the administered formulation. In some embodiments, aerosols intended for delivery to the lung are provided for inhalation through the nose or the mouth. For delivery to the lung, inhaled aerodynamic particle sizes of about less than 10 μm are useful (e.g., about 1 to about 10 microns). Inhaled particles may be defined as liquid droplets containing dissolved drug, liquid droplets containing suspended drug particles (in cases where the drug is insoluble in the suspending medium), dry particles of pure drug substance, drug substance incorporated with excipients, liposomes, emulsions, colloidal systems, coacervates, aggregates of drug nanoparticles, or dry particles of a diluent which contain embedded drug nanoparticles.

In some embodiments, compounds of Formula (I) disclosed herein intended for respiratory delivery (either systemic or local) can be administered as aqueous formulations, as non-aqueous solutions or suspensions, as suspensions or solutions in halogenated hydrocarbon propellants with or without alcohol, as a colloidal system, as emulsions, coacervates, or as dry powders. Aqueous formulations may be aerosolized by liquid nebulizers employing either hydraulic or ultrasonic atomization or by modified micropump systems (like the soft mist inhalers, the Aerodose® or the AERx® systems). Propellant-based systems may use suitable pressurized metered-dose inhalers (pMDIs). Dry powders may use dry powder inhaler devices (DPIs), which are capable of dispersing the drug substance effectively. A desired particle size and distribution may be obtained by choosing an appropriate device.

In some embodiments, the compositions of Formula (I) disclosed herein can be administered to the ear by various methods. For example, a round window catheter (e.g., U.S. Pat. Nos. 6,440,102 and 6,648,873) can be used.

Alternatively, formulations can be incorporated into a wick for use between the outer and middle ear (e.g., U.S. Pat. No. 6,120,484) or absorbed to collagen sponge or other solid support (e.g., U.S. Pat. No. 4,164,559).

If desired, formulations of the disclosure can be incorporated into a gel formulation (e.g., U.S. Pat. Nos. 4,474,752 and 6,911,211).

In some embodiments, compounds of Formula (I) disclosed herein intended for delivery to the ear can be administered via an implanted pump and delivery system through a needle directly into the middle or inner ear (cochlea) or through a cochlear implant stylet electrode channel or alternative prepared drug delivery channel such as but not limited to a needle through temporal bone into the cochlea.

Other options include delivery via a pump through a thin film coated onto a multichannel electrode or electrode with a specially imbedded drug delivery channel (pathways) carved into the thin film for this purpose. In other embodiments the acidic or basic solid compound of Formula (I) can be delivered from the reservoir of an external or internal implanted pumping system.

Formulations of the disclosure also can be administered to the ear by intratympanic injection into the middle ear, inner ear, or cochlea (e.g., U.S. Pat. No. 6,377,849 and Ser. No. 11/337,815).

Intratympanic injection of therapeutic agents is the technique of injecting a therapeutic agent behind the tympanic membrane into the middle and/or inner ear. In one embodiment, the formulations described herein are administered directly onto the round window membrane via transtympanic injection. In another embodiment, the ion channel modulating agent auris-acceptable formulations described herein are administered onto the round window membrane via a non-transtympanic approach to the inner ear. In additional embodiments, the formulation described herein is administered onto the round window membrane via a surgical approach to the round window membrane comprising modification of the crista fenestrae cochleae.

In some embodiments, the compounds of Formula (I) are formulated in rectal compositions such as enemas, rectal gels, rectal foams, rectal aerosols, suppositories, jelly suppositories, or retention enemas, containing conventional suppository bases such as cocoa butter or other glycerides, as well as synthetic polymers such as polyvinylpyrrolidone, PEG (like PEG ointments), and the like.

Suppositories for rectal administration of the drug (either as a solution, colloid, suspension or a complex) can be prepared by mixing a compound provided herein with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt or erode/dissolve in the rectum and release the compound. Such materials include cocoa butter, glycerinated gelatin, hydrogenated vegetable oils, poloxamers, mixtures of polyethylene glycols of various molecular weights and fatty acid esters of polyethylene glycol. In suppository forms of the compositions, a low-melting wax such as, but not limited to, a mixture of fatty acid glycerides, optionally in combination with cocoa butter, is first melted.

Solid compositions can be provided in various different types of dosage forms, depending on the physicochemical properties of the compound provided herein, the desired dissolution rate, cost considerations, and other criteria. In one of the embodiments, the solid composition is a single unit. This implies that one unit dose of the compound is comprised in a single, physically shaped solid form or article. In other words, the solid composition is coherent, which is in contrast to a multiple unit dosage form, in which the units are incoherent.

Examples of single units which may be used as dosage forms for the solid composition include tablets, such as compressed tablets, film-like units, foil-like units, wafers, lyophilized matrix units, and the like. In one embodiment, the solid composition is a highly porous lyophilized form. Such lyophilizates, sometimes also called wafers or lyophilized tablets, are particularly useful for their rapid disintegration, which also enables the rapid dissolution of the compound.

On the other hand, for some applications the solid composition may also be formed as a multiple unit dosage form as defined above. Examples of multiple units are powders, granules, microparticles, pellets, mini-tablets, beads, lyophilized powders, and the like. In one embodiment, the solid composition is a lyophilized powder. Such a dispersed lyophilized system comprises a multitude of powder particles, and due to the lyophilization process used in the formation of the powder, each particle has an irregular, porous microstructure through which the powder is capable of absorbing water very rapidly, resulting in quick dissolution. Effervescent compositions are also contemplated to aid the quick dispersion and absorption of the compound.

Another type of multiparticulate system which is also capable of achieving rapid drug dissolution is that of powders, granules, or pellets from water-soluble excipients which are coated with a compound provided herein so that the compound is located at the outer surface of the individual particles. In this type of system, the water-soluble low molecular weight excipient may be useful for preparing the cores of such coated particles, which can be subsequently coated with a coating composition comprising the compound and, for example, one or more additional excipients, such as a binder, a pore former, a saccharide, a sugar alcohol, a film-forming polymer, a plasticizer, or other excipients used in pharmaceutical coating compositions.

Also provided herein are kits. Typically, a kit includes one or more compounds or compositions as described herein. In certain embodiments, a kit can include one or more delivery systems, e.g., for delivering or administering a compound as provided herein, and directions for use of the kit (e.g., instructions for treating a patient). In another embodiment, the kit can include a compound or composition as described herein and a label that indicates that the contents are to be administered to a patient with cancer. In another embodiment, the kit can include a compound or composition as described herein and a label that indicates that the contents are to be administered to a patient with one or more of hepatocellular carcinoma, colon cancer, leukemia, lymphoma, sarcoma, ovarian cancer, diabetic retinopathy, pulmonary fibrosis, rheumatoid arthritis, sepsis, ankylosing spondylitis, psoriasis, scleroderma, mycotic and viral infections, bone and cartilage diseases, Alzheimer's disease, lung disease, bone/osteoporotic (wrist, spine, shoulder and hip) fractures, articular cartilage (chondral) defects, degenerative disc disease (or intervertebral disc degeneration), polyposis coli, bone density and vascular defects in the eye (Osteoporosis-pseudoglioma Syndrome, OPPG), familial exudative vitreoretinopathy, retinal angiogenesis, early coronary disease, tetra-amelia, Müllerian-duct regression and virilization, SERKAL syndrome, type II diabetes, Fuhrmann syndrome, Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndrome, odonto-onycho-dermal dysplasia, obesity, split-hand/foot malformation, caudal duplication, tooth agenesis, Wilms tumor, skeletal dysplasia, focal dermal hypoplasia, autosomal recessive anonychia, neural tube defects, alpha-thalassemia (ATRX) syndrome, fragile X syndrome, ICF syndrome, Angelman syndrome, Prader-Willi syndrome, Beckwith-Wiedemann Syndrome, Norrie disease, and Rett syndrome.

Evaluation of Biological Activity

The biological activity of the compounds described herein can be tested using any suitable assay known to those of skill in the art, see, e.g., WO 2001/053268 and WO 2005/009997. For example, the activity of a compound may be tested using one or more of the test methods outlined below.

In one example, tumor cells may be screened for Wnt independent growth. In such a method, tumor cells of interest are contacted with a compound (i.e. inhibitor) of interest, and the proliferation of the cells, e.g. by uptake of tritiated thymidine, is monitored. In some embodiments, tumor cells may be isolated from a candidate patient who has been screened for the presence of a cancer that is associated with a mutation in the Wnt signaling pathway. Candidate cancers include, without limitation, those listed above.

In another example, one may utilize in vitro assays for Wnt biological activity, e.g. stabilization of β-catenin and promoting growth of stem cells. Assays for biological activity of Wnt include stabilization of β-catenin, which can be measured, for example, by serial dilutions of a candidate inhibitor composition. An exemplary assay for Wnt biological activity contacts a candidate inhibitor with cells containing constitutively active Wnt/β-catenin signaling. The cells are cultured for a period of time sufficient to stabilize β-catenin, usually at least about 1 hour, and lysed. The cell lysate is resolved by SDS PAGE, then transferred to nitrocellulose and probed with antibodies specific for β-catenin.

In a further example, the activity of a candidate compound can be measured in a Xenopus secondary axis bioassay (Leyns, L. et al. Cell (1997), 88(6), 747-756).

General Procedure

Compounds of Formula (I) of the present disclosure can be prepared as depicted in Scheme 1a.

Compound I, wherein PG is a protecting group such as THP, undergoes Suzuki coupling with Compound II to provide Compound III. In certain embodiments, Compound I (X=Br) undergoes Suzuki coupling with Compound II (Y=—B(OH)₂ or boronate ester) to provide Compound III after removal of the protecting group. In other embodiments, Compound I (X=Br) is first converted to the corresponding boronic acid or boronate ester (not shown), which in turn undergoes Suzuki coupling with Compound II (Y=Br) to provide Compound III after removal of the protecting group. Treatment of Compound III with KOH and I₂ followed by Boc₂O affords the protected iodide IV.

In certain embodiments, when R* is R⁵ (e.g., a six-membered ring), Suzuki coupling between iodide (IV) and boronic acid (V) followed by removal of the protecting groups affords the desired bi-heteroaryl product VI (see, for example, conditions A above).

In other embodiments, when R* is Br or Cl, the resultant Suzuki product can further undergo a second Suzuki coupling to install the R⁵ substituent. In some cases, this procedure is useful when the R⁵ substituent is a five-membered ring. In these embodiments, removal of the protecting groups affords the desired bi-heteroaryl product VI. See, for example, conditions B above.

Compounds of Formula (I) of the present disclosure can be prepared as depicted in Scheme 1.

Scheme 1 describes a method for preparation of 3-(1H-pyrrolo[3,2-c]pyridin-2-yl)-1H-pyrazolo[3,4-c]pyridine compounds (IX) by either converting the 1H-pyrazolo[4,3-b]pyridine (I) to the tributylstannane (II) followed by Migita-Kosugi-Stille coupling to with various bromo compounds to form (III) analogs or by reacting (I) directly with various boronic acids using Suzuki coupling to produce compound (III) analogs. (III) is then deprotected before iodination of (IV) with iodine and potassium hydroxide to produce compound (V) analogs. The 3-iodo-1H-pyrazolo[3,4-c]pyridine (V) nitrogen is then protected with Boc followed by Suzuki coupling with the Boc/SEM protected (1H-pyrrolo[3,2-c]pyridin-2-yl)boronic acid (VII) to form the protected 3-(1H-pyrrolo[3,2-c]pyridin-2-yl)-1H-pyrazolo[3,4-c]pyridine compounds (VIII). Final deprotection of the pyrazole nitrogen yields the desired substituted 3-(1H-pyrrolo[3,2-c]pyridin-2-yl)-1H-pyrazolo[3,4-c]pyridine compounds (IX).

Alternatively, compounds of Formula (I) of the present disclosure can be prepared as depicted in Scheme 2.

Scheme 2 describes an alternative method for preparation of 3-(1H-pyrrolo[3,2-c]pyridin-2-yl)-1H-pyrazolo[3,4-c]pyridine compounds (XIII) by reacting Boc protected 3-iodo-1H-pyrazolo[3,4-c]pyridine (VI) with the Boc/SEM protected (4-bromo-1H-pyrrolo[3,2-c]pyridin-2-yl)boronic acid (X) by Suzuki coupling. A second Suzuki coupling with various boronic acids yields the protected 3-(1H-pyrrolo[3,2-c]pyridin-2-yl)-1H-pyrazolo[3,4-c]pyridine (XII). Final deprotection of the pyrazole nitrogen yields the desired substituted 3-(1H-pyrrolo[3,2-c]pyridin-2-yl)-1H-pyrazolo[3,4-c]pyridine (XIII).

Example 2

The screening assay for Wnt activity is described as follows. Reporter cell lines can be generated by stably transducing cancer cell lines (e.g., colon cancer) or primary cells (e.g., IEC-6 intestinal cells) with a lentiviral construct that includes a Wnt-responsive promoter driving expression of the firefly luciferase gene.

SW480 colon carcinoma cells were transduced with a lentiviral vector expressing luciferase with a human Sp5 promoter consisting of a sequence of eight TCF/LEF binding sites. SW480 cells stably expressing the Sp5-Luc reporter gene and a hygromycin resistance gene were selected by treatment with 150 μg/mL of hygromycin for 7 days. These stably transduced SW480 cells were expanded in cell culture and used for all further screening activities. Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 10-point dose-response curves starting from 10 μM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 384-well white solid bottom assay plates (Greiner Bio-One) with appropriate DMSO backfill for a final DMSO concentration of 0.1%. For Sp5-Luc reporter gene assays, the cells were plated at 4,000 cells/well in 384-well plates with medium containing 1% fetal bovine serum and incubated overnight at 37° C. and 5% CO₂. Following incubation, 20 μl of BrightGlo luminescence reagent (Promega) was added to each well of the 384-well assay plates. The plates were placed on an orbital shaker for 2 min and then luminescence was quantified using the Envision (Perkin Elmer) plate reader. Readings were normalized to DMSO only treated cells, and normalized activities were utilized for EC₅₀ calculations using the dose-response log (inhibitor) vs. response-variable slope (four parameters) nonlinear regression feature available in GraphPad Prism 5.0 (or Dotmatics). For EC₅₀ of >10 μM, the percent inhibition at 10 μM is provided.

Example 3

Representative compounds were screened using the following assay procedure to assess the effect on cell viability as described below.

Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 8-point dose-response curves from 10 μM to 0.0045 μM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 96-well clear bottom, black-walled plates (Corning—Costar).

Approximately 2×103 SW480 colon cancer cells were seeded into each well and allowed to incubate in the presence or absence of compound for four days at 37° C./5% CO₂. Eight replicates of DMSO-treated cells served as controls and cells treated with compound were performed in duplicate.

After incubation, 20 μL of CellTiter-Blue (Promega) was added to each well allowed to incubate for approximately 3 hours. This reagent was a buffered solution which contains resazurin, metabolically active cells were able to reduce rezarurin (blue) into resorufin (pink) which was highly fluorescent. This measured fluorescence was used as a readout for cell viability.

After incubation, the plates were read at Ex 560 nm Em 590 nm (Cytation 3, BioTek). Dose-response curves were generated and EC₅₀ concentration values were calculated using non-linear regression curve fit in the GraphPad Prism (San Diego, Calif.) or Dotmatics' Studies Software (Bishops Stortford, UK). For EC₅₀ of >10 μM, the percent inhibition at 10 μM is provided.

Example 4

Representative compounds were screened using primary human fibroblasts (derived from IPF patients) treated with TGF-β1 to determine their ability to inhibit the fibrotic process.

Human Fibroblast Cell Culture: Primary human fibroblasts derived from IPF patients (LL29 cells) [¹Xiaoqiu Liu, et. al., “Fibrotic Lung Fibroblasts Show Blunted Inhibition by cAMP Due to Deficient cAMP Response Element-Binding Protein Phosphorylation”, Journal of Pharmacology and Experimental Therapeutics (2005), 315(2), 678-687; ²Watts, K. L., et. al., “RhoA signaling modulates cyclin D1 expression in human lung fibroblasts; implications for idiopathic pulmonary fibrosis”, Respiratory Research (2006), 7(1), 88] were obtained from American Type Culture Collection (ATCC) and expanded in F12 medium supplemented with 15% Fetal Bovine Serum and Penicillin/Streptomycin.

Compound Screening: Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:2, 11-point dose-response curves from 10 μM to 1.87 nM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 384-well clear bottom assay plates (Greiner Bio-One) with appropriate DMSO backfill for a final DMSO concentration of 0.1%. LL29 cells are plated at 1,500 cells/well in 80 μL/well F12 medium supplemented with 1% Fetal Bovine Serum. One hour after addition of the cells, TGF-β1 (Peprotech; 20 ng/mL) was added to the plates to induce fibrosis (ref. 1 and 2 above). Wells treated with TGF-β1 and containing DMSO were used as controls. Cells were incubated at 37° C. and 5% CO₂ for 4 days. Following incubation for 4 days, SYTOX green nucleic acid stain (Life Technologies [Thermo Fisher Scientific]) was added to the wells at a final concentration of 1 μM and incubated at room temperature for 30 min. Cells were then fixed using 4% formaldehyde (Electron Microscopy Sciences), washed 3 times with PBS followed by blocking and permeabilization using 3% Bovine Serum Albumin (BSA; Sigma) and 0.3% Triton X-100 (Sigma) in PBS. Cells were then stained with antibody specific to α-smooth muscle actin (αSMA; Abcam) (ref. 1 and 2 above) in 3% Bovine Serum Albumin (BSA; Sigma) and 0.3% Triton X-100 (Sigma) in PBS, and incubated overnight at 4° C. Cells were then washed 3 times with PBS, followed by incubation with Alexa Flor-647 conjugated secondary antibody (Life Technologies [Thermo Fisher Scientific]) and DAPI at room temperature for 1 hour. Cells were then washed 3 times with PBS and plates were sealed for imaging. αSMA staining was imaged by excitation at 630 nm and emission at 665 nm and quantified using the Compartmental Analysis program on the CellInsight CX5 (Thermo Scientific). Dead or apoptotic cells were excluded from analysis based on positive SYTOX green staining. % of total cells positive for αSMA were counted in each well and normalized to the average of 11 wells treated with TGF-31 on the same plate using Dotmatics' Studies Software. The normalized averages (fold change over untreated) of 3 replicate wells for each compound concentration were used to create dose-responses curves and EC₅₀ values were calculated using non-linear regression curve fit in the Dotmatics' Studies Software. For EC₅₀ of >10 μM, the percent inhibition at 10 μM is provided.

Example 5

Representative compounds were screened using primary human mesenchymal stem cells (hMSCs) to determine their ability to induce chondrogenesis (process by which cartilage is developed).

Human Mesenchymal Stem Cell Culture: Primary human mesenchymal stem cells (hMSCs) were purchased from Lonza (Walkersville, Md.) and expanded in Mesenchymal Stem Cell Growth Media (Lonza). Cells between passage 3 and 6 were used for the experiments.

Compound Screening: Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 6-point dose-response curves from 2700 nM to 10 nM) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 96-well clear bottom assay plates (Greiner Bio-One) with appropriate DMSO backfill for a final DMSO concentration of 0.03%. hMSCs were plated at 20,000 cells/well in 250 μL/well Incomplete Chondrogenic Induction Medium (Lonza; DMEM, dexamethasone, ascorbate, insulin-transferrin-selenium [ITS supplement], gentamycin-amphotericin [GA-1000], sodium pyruvate, proline and L-glutamine). TGF-β3 (10 ng/mL) was used as a positive control for differentiation while negative control wells were treated with 75 nL DMSO for normalization and calculating EC₅₀ values. Cells were incubated at 37° C. and 5% CO₂ for 6 days. To image chondrogenic nodules, the cells were fixed using 4% formaldehyde (Electron Microscopy Sciences), and stained with 2 μg/mL Rhodamine B (Sigma-Aldrich) and 20 μM Nile Red (Sigma-Aldrich) [Johnson K., et. al, A Stem Cell-Based Approach to Cartilage Repair, Science, (2012), 336(6082), 717-721]. The nodules imaged (4 images per well at 4× magnification) by excitation at 531 nm and emission at 625 nm and quantified using the CellInsight CX5 (Thermo Scientific). Number of nodules in each well was normalized to the average of 3 DMSO treated wells on the same plate using Excel (Microsoft Inc.). The normalized averages (fold change over DMSO) of 3 replicate wells for each compound concentration were calculated. Due to solubility limitations of some of the compounds, curve fitting was incomplete leading to inaccurate EC₅₀ determinations.

Using TGF-β3 as a positive control, the concentration of representative compounds required to induce 50% levels of chondrogenesis is reported. In addition, the maximum activity of each compound and the respective dose that each compound reached maximum chondrogenesis activity is reported. Table 5 shows the activity of representative compounds as provided herein.

Compound Screening: THP-1 cells were cultured in basal media with 1% FBS for 24 hours before the start of the assay. Each compound was dissolved in DMSO as a 10 mM stock and used to prepare compound source plates. Serial dilution (1:3, 10-point dose-response curves starting from 10 M) and compound transfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.) into 384-well white low volume assay plates (Greiner Bio-One) with appropriate DMSO backfill for a final DMSO concentration of 0.1%. THP-1 cells were plated at 5000 cells/well in the 384-well plates and incubated at 37° C. for 2 h. 500 ng/mL of LPS was added after 2 hours and cells were incubated for another 22 hours at 37° C. Plates were spun in a centrifuge for 1 minute at 10,000 rpm and a mixture of anti-IL6 XL665, and anti-IL6 Cryptate diluted in reconstitution buffer (Cisbio Inc.) was added to each well. Following incubation for 3 hrs at room temperature, Homogeneous Time-Resolved Fluorescence (HTRF) was measured using the Envision (Perkin Elmer) at 665 nm and 620 nM. The ratio of fluorescence at 665 nm to 620 nm was used as a readout for IL6 quantification. All samples were processed in duplicate. Readings were normalized to DMSO treated cells and normalized activities were utilized for EC₅₀ calculations using the dose-response log (inhibitor) vs. response-variable slope (four parameters) nonlinear regression feature available in GraphPad Prism 5.0 (or Dotmatics). For EC₅₀ of >10 μM, the percent inhibition at 10 μM is provided.
